RN424 , 4x 8TB WD Red Plus failing after 120 days?
This problem is with a RN424 with 4x 8TB WD80EFAX, all identical HDs purchased at the same time as the 424. The system has 6.10.4 Hotfix1 and has been up for 120 days, I had not even transferred all ...
The disk is SO dead that the WD utilities (neither Lifeguard Diagnostic DLGDIAG 1.37 nor the “Dashboard”) could not even see it.
Seagate Seatools for Windows saw it, tested it and failed it

Victoria also saw it, as fail it immediately too.
On the 424 I run the extended disk test as adviced. The test completed on Saturday afternoon. I received an email stating that it had been completed, no mention of any Warning or Errors, I presumed it was ok, but I just downloaded the logs, and in volume.log, the last line reads:
“data disk test 2021-07-30 20:54:30 2021-07-31 13:49:00 pass”.
The other advice was:
“The bay in the NAS might also have failed - if you have a spare disk, you might try doing a factory install (with only the spare disk inserted, in bay 1). Then power down and move the disk to bay 2. Power up, and make sure it works. If you try this test, label the disks by slot as you remove them.”
Do you mean a factory default as in
or via Option 2 in the boot menu (P97 on the HM manual) – (I presume it is the same operation)
I guess that it would format the ”spare disk” (I don’t have a free one, but I suppose I can re-clone one 50Gb hd with a spare W7 copy I have)
This often happens, which is normal. I mean the WD RED disks in the same batch can fail in the high probability. The NAS players around me accept it very early, and are not friendly to the WD RED.

AFAICT we are seeing just one drive failure here, not multiple. Usually when I see multiple early failures I am thinking there might have been damage in storage or shipment. But failures at ~120 days are somewhat unusual - in my experience they either fail out-of-the-box or run quite a bit longer. In any event, they can and do fail at any time (which is why you need backups).
FWIW, the WD80EFAX is a WD Red Plus drive, not a WD Red. WD rebranded about a year ago. The current WD Red models are all SMR, the Red Plus and Red Pro models are CMR. I don't recommend SMR for ReadyNAS. BTW, Seagate Barracudas are also largely SMR.
I have mostly WD Red Plus drives (mixed with a few Seagates), including three of this particular model - and haven't seen any unusual failure rates with either. As far as I can tell, the Seagate Ironwolf and WD Red Plus are both reliable, and users here seem satisfied with both lines. In general, NAS-purposed or Enterprise disks are good options for ReadyNAS (other than the SMR WD Reds).
Yes!
In my machine I use the red drive, purple drive, black drive, and Seagates considering of CMR not SMR, and NETGEAR recommendation page:

At last in my budget I prefer to the purple drive and Seagates.

Although Netgear will qualify desktop drives, I don't recommend them. One reason is that over time the manufacturers will change them. Barracudas for example are now SMR, but they weren't a few years ago. NAS-purposed or Enterprise (excluding those pesky SMR Reds) are safe choices, even if they aren't on the HCL (which tends to lag new drive introductions by many months).

FWIW, I used a Black drive (quite a few years ago now), and found it was quite noisy. But I'm sure the drive tech has changed since then. In any event, I do check the acoustic and power specs when I am considering a new disk model.
Purple (surveillance) drives are tuned for write performance when streaming, so read performance might be somewhat lower than NAS-purposed. They should work reliabily though, and are unlikely to be SMR.
Budget is of course a consideration. I do look at prices when I purchase new drives - my most recent purchase was an on-sale Seagate Exos which was actually cheaper than Ironwolf or WD Red Plus. Sometimes there can be a big delta between Seagate and WD, though usually the gap is pretty narrow.
